Abstract
The utility model discloses a kind of LCD TV backlight module with New-support, the LED lamp bead comprising backboard and be evenly installed on backboard, backboard is provided with some supports for supporting light guide plate between LED lamp bead, described support is square column structure, by the one-body molded gained of transparent material.The utility model can effectively weaken support shadow; Because support shadow can effectively weaken, therefore the display effect of LCD TV can improve.
Description
Technical field
The utility model relates to LCD TV backlight technology, is specifically related to a kind of LCD TV backlight module.
Background technology
Backlight module is the important component part of LCD TV.In LCD TV, backlight module is arranged in liquid crystal panel behind, and during work, backlight module is luminous, and light forms required display frame after liquid crystal panel.Be provided with light guide plate between backlight module and liquid crystal panel, the effect of light guide plate is that the light that backlight module is produced can be softer.In order to make position between backlight module and light guide plate fix, backlight module needs the support being provided with supporting light guide plate.In prior art, these supports are all for columniform, can reflect when the light sent is mapped on rack surface by LED lamp bead.Because the reflective surface area at rack surface place is comparatively large, reflection ray does not have rule, and the light through reflection effectively can not compensate the light intensity of corresponding lamp side, and support shadow therefore can be caused obvious, produces harmful effect to the display effect of LCD TV.
Summary of the invention
In order to solve above technical problem, the utility model provides a kind of LCD TV backlight module with New-support, and it can effectively weaken support shadow, effectively promotes the display effect of LCD TV.
The technical scheme that the utility model adopts for technical solution problem is:
With the LCD TV backlight module of New-support, the LED lamp bead comprising backboard and be evenly installed on backboard, backboard is provided with some supports for supporting light guide plate between LED lamp bead, and described support is square column structure, by the one-body molded gained of transparent material.
As preferred embodiment, described LED lamp bead is according to square dot matrix rule distribution, and the square center position that described rack arrangement forms in four adjacent LED lamp pearls, four sides of support are relative with these four LED lamp bead respectively.
As preferred embodiment, described support adopts PC material or the one-body molded gained of PMMA material.
The beneficial effects of the utility model are: the utility model adopts square column and is transparent support, the light transmition that lamp pearl sends is to refraction and reflection can occur during rack surface simultaneously, directly being reflected back light in air can the light intensity of the corresponding lamp side of effective compensation, light intensity in its corresponding region and other position difference are reduced, can effectively weaken support shadow; Wherein there is most light can arrive the opposite side of support through support, the light of this part can compensate the light intensity of support opposite side, compared to the light tight cylindrical holder of tradition, transmitted light component is added in the light at support shadow place here, the light-intensity difference of corresponding light intensity and other positions obviously reduces, and such benefit can effectively weaken support shadow exactly; Because support shadow can effectively weaken, therefore the display effect of LCD TV can improve.
Accompanying drawing explanation
Be further detailed below in conjunction with the drawings and specific embodiments:
Fig. 1 is structural representation of the present utility model.
Symbol description: 1-backboard, 2-LED lamp pearl, 3-support.
Detailed description of the invention
Backlight module of the present utility model is applied on LCD TV.As shown in Figure 1, the entirety of backlight is a backboard 1, and backboard 1 is provided with LED lamp bead 2 and support 3.LED lamp bead 2 is evenly installed on backboard 1, and in general embodiment, LED lamp bead 2 adopts the mode of LED lamp bar to install.Support 3 is fixed on support 3, and LCD TV has assembled rear light guide plate and has been positioned on backboard 1, and support 3 is for supporting light guide plate.When embody rule, the quantity of support 3 is arranged as required.
As shown in the figure, support 3 of the present utility model is square column structure, and it is by the one-body molded gained of transparent material.This transparent square column support is interspersed between LED lamp bead 2, during work, refraction and reflection can be there is in the light transmition that LED lamp bead 2 sends to during support 3 surface simultaneously, directly being reflected back light in air can the light intensity of the corresponding lamp side of effective compensation, light intensity in its corresponding region and other position difference are reduced, can effectively weaken support shadow; Wherein there is most light can arrive the opposite side of support 3 through support 3, the light of this part can compensate the light intensity of support 3 opposite side, compared to the light tight cylindrical holder of tradition, transmitted light component is added in the light at support shadow place here, the light-intensity difference of corresponding light intensity and other positions obviously reduces, and such benefit can effectively weaken support shadow exactly.
When embody rule, support 3 can adopt PC material or the one-body molded gained of PMMA material.
In the preferred embodiment, LED lamp bead 2 is according to square dot matrix rule distribution, and support 3 is arranged in the square center position of four adjacent LED lamp pearl 2 compositions, and four sides of support 3 are relative with these four LED lamp bead 2 respectively.Most of light of four LED lamp bead 2 injections vertically can penetrate support 3 and arrive another side place, and support shadow can obtain optimum reduction.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
